The present church was built in 1762 (Wikipedia gives the consecration year as 1767) after the medieval church that had previously stood on the site was demolished. Sections of the old north wall were retained and incorporated into the new building, and a 17th-century drawing by Johan Peringskiöld shows the earlier church as a long room supported by heavy buttresses.
During the 19th century the church was remodelled, gaining a ridge turret, while the west gable was given stone ornamentation to mark it as the main façade. The unusual round bell tower, unique in Södermanland, was designed by Lieutenant Colonel Fredrik Wilhelm Hoppe and built in 1776 on the site of the former Lerbo courthouse; it is said to have also served at times as a granary. Of the tower's three bells, the middle one dates from the 1280s, the largest (around 1000 kg) from 1501, and the smallest was cast in Stockholm in 1773 — making it home to one of the county's oldest surviving church bells.
Inside, the oldest fitting is a sandstone font from the 1100s, standing beneath a painting added in 1943. The altarpiece, depicting the Resurrection of Christ, was painted in 1840 by the self-taught artist G. A. Engman, a former valet at Claestorp Manor. The pulpit was made in 1783 at Stäringe estate and donated to the church by the provincial governor Gabriel Falkenberg. A militia banner from 1710, belonging to the Lerbo company, hangs on the organ loft.
The church holds a range of notable silver, including a gilded chalice and paten made by Nyköping goldsmith Johan Jacob Ulfsberg in 1800, a wafer box from 1657 bearing the initials and arms of the Sparre and Berendes families, and a bridal crown purchased in 1666. Several brass chandeliers of varying age and design, including an unusual eight-armed piece decorated with a figure of Jupiter riding an eagle, add further interest to the interior.
The church's first organ was installed in 1855, and its facade survives today, though the current instrument dates from 1929, built by Alfred Fehrling of Stockholm and later renovated.
